Puzzle Strike Strategy Guide
This huge 100-page strategy guide (it's a physical book, by the way!) was written by tournament players, in an effort to pass on their collective Puzzle Strike knowledge to you. It covers all 20 characters across the base set and the Shadows expansion, as well as every puzzle chip in the game.
You'll learn all sorts of combos, how to manage your money and purple density, when to cycle your redraws at the right times, and about the rushdown / defense / econ triangle of strategies.
